[Objective]To compare the nutritional content of muscle in various parts of Channa argus to provide scientific basis for the nutritional value of Channa argus muscle.[Method]By means of international-standard testing methods,the normal nutritional content as well as amino acids and fatty acid content of the four parts of Channa argus,that is,the front back,middle back,tail,and abdomen is measured separately.[Result]Among the four muscle parts,the parts with the highest levels of water,ash,and crude protein are the middle back,abdomen,and tail.Abdominal meat contains the highest fat content.Normal nutritional content measurements for all four parts displays significant differences(P<0.05).Eighteen amino acids are detected in all four parts of the muscle.Among them,Glutamic acid content is the highest and Cysteine content stays the lowest.The percentage of essential amino acids and delicious amino acids in the total amount of amino acids ranges from 32.23％to 35.41％and 41.10％to 44.17％;abdominal meat had the highest levels of saturated fatty acids,monounsaturated fatty acids,and polyunsaturated fatty acids.[Conclusion]Testing the muscle of Channa argus on a sectional basis would furnish dissection for the nutritional content of freshwater fish with new perspective,and provide guidance for those who take Channa argus as aliment.
